Abstract
The invention relates to a thread jack with the rapid jacking function. The thread jack comprises a supporting ring, a jacking mechanism and a base sleeve which are connected in sequence. The base sleeve is composed of a hollow cylinder at the upper end and a hollow circular truncated cone at the lower end. A pair of small holes are correspondingly formed in the two sides of the hollow cylinder. The jacking mechanism comprises a jacking rod, a fixed insertion rod, a threaded rod and a handle. The jacking rod is arranged in the base sleeve and the top end of the jacking rod is provided with a threaded hole with which the threaded rod is connected. Multiple through holes A are axially and evenly distributed in the jacking rod. A circular channel in which the fixed insertion rod is inserted is formed by the through holes A and the small holes in the base sleeve. The fixed insertion rod is arranged in the circular channel. The threaded rod is connected to the top end of the jacking rod and a through hole B in which the handle is inserted is formed in the threaded rod in the radial direction. The thread jack has the beneficial effects that the jacking rod is arranged, an object can be located in the jacking range rapidly, and the thread jack can be suitable for jacking the high object.
Description
Technical field
The present invention relates to a kind of weight-lifting equipment, be specifically related to a kind of jack.
Background technology
Screw jack is by manpower by screw pair transmission, and screw rod or ut socket lift the small lifting equipment of part as top.Normal spiral jack supports weight by screw thread self-locking effect, simple structure, but driving efficiency is low, and the higher object in position is lifted on top, and lifting body ascending velocity is slow, and return is slow.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of screw jack of fast servo
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of screw jack of fast servo, and its innovative point is: comprise the hypanthium, lifting body and the base sleeve that are connected successively; Described base sleeve is made up of the hollow circular cylinder of upper end and the hollow round table body of lower end; Described hollow circular cylinder both sides have a pair corresponding aperture; Described lifting body comprises lifting pin, fixing inserted link, thread rod and handle; Described lifting pin is arranged in base sleeve, and its top has a tapped bore connected for thread rod; Described lifting pin is axially evenly distributed with some through hole A, and described through hole A and the aperture on base sleeve forms the circular channel that inserted link grafting is fixed in confession; Described fixing inserted link is arranged in this circular channel; Described thread rod is connected to lifting pin top, and its radial direction has the through hole B for handle grafting.
Further, described lifting pin cross section is T-shaped.
Further, described fixing inserted link one end has a stop protrusion, and the other end has a movable stop pin.
The invention has the advantages that:
(1) a kind of fast jack of the present invention has a lifting pin, object fast speed can be made to be within the scope of jacking, can adapt to the jacking being in higher building body.
(2) head diameter of lifting pin is greater than the diameter of bottom, and the center of lifting pin head has screw rod, and larger diameter can bear the larger power that screw rod applies.
(3) fixing inserted link is plugged on lifting pin, and the backing block on it and movable stop pin be stuck fixing inserted link firmly, makes it can not left and right play, affects fixed effect.
Accompanying drawing explanation
Fig. 1 is the screw jack of a kind of fast servo of the present invention.
Detailed description of the invention
As shown in Figure 1, the invention discloses a kind of screw jack of fast servo, comprise the hypanthium 1, lifting body and the base sleeve 5 that are connected successively; Base sleeve 5 is made up of the hollow circular cylinder of upper end and the hollow round table body of lower end; Hollow circular cylinder both sides have a pair corresponding aperture; Lifting body comprises lifting pin 3, fixing inserted link 8, thread rod 2 and handle 9; Lifting pin 3 is arranged in base sleeve 5, and lifting pin 3 cross section is T-shaped, and that is, the diameter on jacking 3 bar top is larger than the diameter of bottom, and its top has a tapped bore connected for thread rod 2; Lifting pin 3 is axially evenly distributed with some through hole A6, and through hole A6 and the aperture on base sleeve 5 forms the circular channel that inserted link 8 grafting is fixed in confession; Fixing inserted link 8 is arranged in this circular channel, and fixing inserted link 8 one end has a stop protrusion 7, and the other end has a movable stop pin 4, firmly the side-to-side movement of the fixing inserted link of restriction; Thread rod 2 is connected to lifting pin 3 top, and its radial direction has the through hole B for handle 9 grafting; The connection of thread rod 2 and hypanthium 1 is prior art, does not repeat them here.
During use, the through hole A6 on the aperture on base sleeve 5 and lifting pin 3, to the length be applicable to, aims at by adjustment lifting pin 3, insert fixing inserted link 8, be stoppered movable stop pin 4, lifting pin 3 and base sleeve 5 are fixed, insert with handle 9 in the through hole B on thread rod 2, turning handle 9, thread rod 2 rotates and upward movement, thus hypanthium 1 holds out against object, continues turning handle 9, object continues to rise, until reach desirable height; Pack up this jack also easily quick, only base sleeve 5 and lifting pin 3 need be resetted, thread rod 2 resets, because lifting pin 3 assume responsibility for most height, so, pack up thread rod 2 very convenient.
More than show and describe groundwork of the present invention and principal character.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
Claims (3)
